rectangle from geometric center

[Ch.giacomo]

Good morning, I would like to draw rectangles with autocad from their geometric center, does anyone know how to do it?
I often find myself in the situation of creating a rectangle in the center of a circle and it would be really convenient to leave right from the center, now I have to create it on the side and then move it.
Thank you.

I train you a free cad studio program (www.cadstudio.cz) )
by us appload per caricature in autocade e poi cenrect to start the new command

Thank you tomorrow!

 

[Ch.giacomo]

great, it solves some situations!! sin can not give the size to keyboard! !
Thank you.

I don't use autocad for a long time, but I would try with a four-sided polygon in which he asks the center...

the only 4-sided polygon that you can draw from the center is the square

a square that then remains at 45 degrees.. I looked a lot on the internet but nobody seems to serve this thing. .
I don't know anything about lisp so patience! !

 

[Zac69]

I know, but while you make the square at least one share you can give it. after you explode and iron it in the other way. I repeat: I thought so, but I haven't used autocad for a while.
in mechanical there is a command that does exactly what you are looking for, but in autocad no.

 

[Tristan]

to iron it does not need to explode, and anyway it would not solve anything by ironing it.
Anyway, it would take us much less to do as it does now, i.e. a rectangle of size given in incorrect position, and then move it to the new center.

You can use a lisp I did years ago... but it still works: box-center

asks to click at the point that represents the center, then give the measure of the base and height.
giving the measure of height, you accept the first measure and then you get a square.

 

[Ch.giacomo]

Thank you so much!! it works perfectly! You took me a daily boredom! !
I'm very grateful.

Good morning, x11start I wanted to ask you an info about your lisp box-center. .
it works great but it is possible that it is incompatible with another lisp, in the sense that if I have loaded (box-centre) and (verifqta) that I attach, when I give the command they mix me... writing box-centre makes me start the other lisp... (depending on the last load)
How is it possible? Thank you.

 

[x11start]

also the lisp "verifqta" is my work.... and I must admit that many of my lisp are not well "closed": This means that you load one then throw the previous one... there may be malfunctions. My advice is simply to recharge what you want to launch: I put them in a menu that loads them and throws them not "off" of these problems, because the lisp is recharged every time.

 

[Ch.giacomo]

Good! I will make a custom menu for the lisp so that you have brought them by clicking!
